In The Sherlock Society, what does Yadi suggest using to search the area where the Lost City is believed to be?

• A. His drone
• B. A metal detector
• C. A map
• D. A dog

Answer: (A)

Choosing an effective tool for surveying a large, uncertain area is being tested. Yadi’s suggestion to use a drone provides an aerial view that can quickly cover vast terrain and reveal features or anomalies that aren’t noticeable from the ground. With a drone, you can monitor progress in real time, reach otherwise inaccessible spots, and identify promising areas for closer ground inspection, which is essential when searching for something as elusive as a Lost City. A static map wouldn’t reflect current conditions, a metal detector is too slow and limited to metal on the ground, and a dog can help with scents but isn’t reliable for surveying large areas or locating buried structures. Using a drone combines speed, safety, and broad visibility, making it the best choice for this kind of search.
